Description

The Arctic Diamond Edition captures pure elegance with a clean, icy aesthetic and refined detailing. Its 31mm case frames a crisp silver-white dial set with sparkling crystal hour markers, delivering a bright, luxurious presence on the wrist. The fluted bezel and polished jubilee-style bracelet complete the look, giving it a timeless, high-end finish suited for any occasion.

Powered by the reliable Seiko NH05 automatic movement, it offers smooth, self-winding precision without the need for a battery. A scratch-resistant sapphire crystal protects the dial, while the stainless steel construction ensures durability and comfort. Hand-assembled with care, this piece blends classic sophistication with everyday versatility.
